Capella 0.8.2

Primary tabs


Much more than just yet another modelling tool, Capella is a model-based engineering solution that has been successfully deployed in a wide variety of industrial contexts. Based on a graphical modelling workbench, it provides systems, software and hardware architects with rich methodological guidance relying on Arcadia, a comprehensive model-based engineering method.

  • Ensure engineering-wide collaboration by sharing the same reference architecture
  • Master the complexity of systems and architectures
  • Define the best optimal architectures through trade-off analysis
  • Master different engineering levels and traceability with automated transition and information refinement

Capella 0.8.2 features:

  • Enhancements for State Machines
  • Bugfixes


API Certification: 

The project leadership certifies that the APIs in this release are "Eclipse Quality".

Architectural Issues: 

There is no specific issue detected on the Capella solution architecture.

Capella is a modular platform which uses Eclipse modeling components, Sirius and EMF Diff/Merge, and a PolarSys component, Kitalpha.
The role of Kitalpha is twofold:

  • Providing basic components from the Kitalpha Core Technology Kit (e.g. Transposer)
  • Extending Capella with Viewpoints for System co-engineering

Capella is extensible with add-ons (available in a specific Git repository)

  • System to Subsystem Transition
  • XML Pivot
  • HTML DocGen

A first preliminary version of Capella Studio has been made available through Capella website. Capella Studio aims at creating Capella Viewpoints (also available in a specific Git repository).

Security Issues: 

There is no specific security issue detected on the Capella solution.

Non-Code Aspects: 

All communication links regarding Capella solution are up-to-date:

  • Wiki with "News" section
  • Website with different sections:
    • Installation instructions on Getting Started page
    • Community links
    • Download page for Capella solution and Documentation
    • Events around Capella solution (conferences, talks, etc.)
    • Links to YouTube dedicated channel for Capella as well as LinkedIn page and Twitter
  • Forum
  • Project page
  • In-Flight Entertainment and Alarm Clock sample use-cases has been made available through Capella website with associated documentation
  • Bugzilla, Hudson instance.

The quality is ensured through:


Usability Details: 

Capella solution UI is compliant with User Interface Guidelines.
The workbench is decomposed as shown in the Wiki figure:

  • On the left, the Capella "model" project explorer
  • In the center, the Overview for Arcadia phases and Diagrams editors
  • Property views and Semantic browser at the bottom
  • Fast linker (optional) in the bottom left-hand corner providing facilities for diagrams edition
End of Life: 

No APIs and significant features are intended to be deprecated in a near future.
Improvements this year on Capella solution feature:

  • Performance increase
  • Ergonomics
  • Palettes customization
  • Bugfix
  • Development of extensions / connectors towards specialty environments

Capella solution implement the Arcadia model-based engineering method for systems, hardware and software architectural design.
Before Arcadia is officially and entirely published, a light introduction explaining the rationale and main concepts is now available for download on the website.
